Go to tboltusa.com and go nuts! I think the most noticeable would be the tb v2 head (from what I've read). I'm in the same boat but with a zs155 that I wanna start adding stuff to.
they call it a 160 but it's 155cc. It is zongshen. Not yx.What makes this engine a HO, or it this just a rebranded YX160?
Not IMO.Is the yx 160 a better motor?
Haha, yes.Got a YX coming my way with some slutty mods so I know it's a ho.
